Is “SW4SW” a thing?

In the trans community we have something called t4t (short for trans for trans). It refers to the practice of trans people dating other trans people to avoid all the possible complications that can come with dating someone who doesn’t belong to the same marginalized group as you.

This got me curious, is it common for sexworkers to date eachother in the same vein? I imagine dating a civilian can be tough, so do SW see this as a possible way around those difficulties?
